We are a trusted deck builder in Toronto, Richmond Hill, Markham, and other nearby areas.
Splitting your deck project among a designer, permit specialist, and builder can seem flexible, but it often creates costly gaps between planning and construction. A drawing may look right on paper yet fail to reflect site conditions, permit requirements, or the way the deck will actually be built.
Working with one experienced Markham deck company can simplify communication, reduce delays, and keep responsibility with a single team. The designer, permit specialist, and construction crew can coordinate from the beginning, helping the approved plans match the finished deck.
This guide explains how the full deck building process works, the risks of splitting the job, the potential cost and timeline differences, and what to check before choosing a contractor.
Key Takeaways
- A single deck company handling design, permits, and construction can reduce coordination issues and keep one team responsible for your project
- Integrated teams may catch design issues early because the builder and designer work together from the start
- In Markham, most decks over 600mm high or attached to your house need a permit, and experienced companies manage this process for you
Understanding the Deck Building Process
Building a deck involves several steps from initial design through permits to construction. Understanding these phases helps with planning your timeline and budget.
Types of Deck Projects
The type of deck you build affects materials, permits, and cost.
Ground-level decks sit close to the ground and often serve as patio replacements. These are usually straightforward builds. They typically do not need guardrails and might not require permits if under 600mm high and not attached to your house.
Raised decks are elevated above grade and almost always need permits. These decks require proper footings, structural support, and guardrails.
Multi-level decks are suitable for sloped yards or when you want separate outdoor zones. They are more complex and take longer to build.
Pool decks have specific requirements for drainage, pool barrier regulations, and materials that remain safe in hot weather.
Phases of a Deck Build
Every deck project moves through distinct phases:
Design and planning: Measure your space, discuss intended use, and create drawings that show layout, dimensions, and materials. These drawings are used for permit applications.
Permit application: For most attached or raised decks, this typically takes 4-6 weeks for approval in Markham. The city reviews your plans for building code compliance.
Site preparation and footings: After permits are issued, mark out the deck location, dig holes for footings (usually to 1.2 metres for frost protection), and pour concrete.
Framing and structure: Install posts, beams, and joists according to the design.
Decking and railings: Install surface boards, build the railing system, add stairs if needed, and complete finishing details.
Local By-Laws and Permit Requirements
Markham has specific rules about when you need a building permit for deck construction.
You need a permit if your deck is:
- More than 600mm (about 24 inches) above the ground
- Attached to your house
- Large enough to trigger city size thresholds
The permit process ensures your deck meets structural standards and includes required safety features. Inspections occur at key stages, such as after footings are poured and when construction is complete.
Permit applications require detailed drawings showing dimensions, materials, footing depths, and structural connections. Processing typically takes 4-6 weeks.
Design Considerations for Your Outdoor Space
Before thinking about permits or construction, clarify how you want your deck to function. Good design decisions early can help avoid expensive changes later.
Assessing Your Needs and Lifestyle
Consider how you will use your deck. Will it be for family dinners, quiet mornings, or entertaining? Think about features like hot tubs or outdoor kitchens.
The sun’s path across your yard may influence whether you need a pergola or shade structure. Deck orientation can affect usability.
Estimate how many people will use the space. Consider how the deck connects to indoor areas for convenience.
Choosing Materials and Finishes
Common options include pressure-treated wood, composite, and PVC.
- Pressure-treated wood: Lower upfront cost, typically $25-35 per square foot. Requires regular staining.
- Composite: Costs $40-55 per square foot. Low maintenance and resists rot and splinters.
- PVC: Premium option at $50-60 per square foot. Handles moisture well and retains color.
Material choice affects maintenance needs, comfort, and budget.
Space Planning and Layout Ideas
Most decks in Markham range from 200 to 400 square feet. This size accommodates a dining table, lounge chairs, and walking space.
Multi-level decks suit sloped properties and create zones for different activities. Built-in seating can save space.
Ensure proper drainage so water does not pool or flow toward your foundation.
Railing style influences the openness of your deck. Glass panels maintain sight lines, while wood or metal balusters are more traditional. Decks close to the ground may not require railings.
Importance of Professional Permit Drawings
Permit drawings show the City of Markham what you plan to build and where it will be located. Accurate drawings can help avoid delays and costly mistakes.
What Are Permit Drawings?
Permit drawings are technical plans showing your deck’s measurements, materials, and structural details. They include a site plan, floor plans with exact dimensions, and structural details like attachment methods and beam sizes.
The City of Markham requires these drawings to meet specific standards, including setbacks, guardrail heights, stair dimensions, and footing depths. Larger or taller decks may require an engineer’s stamp.
Inaccurate or incomplete drawings often lead to deficiency letters and project delays.
Benefits of Compliance with Markham Regulations
Compliant permit drawings are more likely to be approved quickly, reducing the need for resubmissions.
Accurate drawings help ensure construction matches what the city approved, making inspections smoother.
Having proper permit documentation can also be important when selling your home, as buyers may request proof that the deck was built with permits.
Finding the Right Deck Company in Markham
Not every deck builder in Markham operates the same way. Knowing what credentials matter and which questions to ask can help you select a company that can manage your project from start to finish.
Evaluating Contractor Credentials
Check for insurance and WSIB coverage. Ask to see current certificates.
Confirm if the company pulls its own permits and has experience with Markham’s requirements, such as the 1.2-metre frost line.
Ask for recent references from Markham projects. Contact past clients about timeline accuracy, communication, and problem resolution.
Review warranty details in writing. Clarify what is covered and who handles warranty work.
Questions to Ask Before Hiring
- Can you handle design, permit drawings, and construction in-house?
- What is your typical timeline from first meeting to completed deck?
- How do you assist with material selection?
- What is your process if changes are needed mid-project?
- Who will be on-site daily, and how is progress communicated?
Advantages of a Single Contractor Approach
Working with one deck company for design, permits, and construction can offer clearer communication, faster timelines, and better quality control.
Streamlining Communication
When separate professionals are hired for design, permits, and construction, the homeowner often coordinates between them. This can lead to delays and miscommunication.
A single company manages all communication internally. The design team, permit specialists, and construction crew work together, reducing the need for the homeowner to act as a go-between.
This approach also reduces the risk of disputes over responsibility.
Saving Time and Reducing Stress
A single-company approach can shorten the overall project timeline by overlapping phases such as design and permit preparation, and by scheduling crews in advance.
Homeowners benefit from having one contract, one payment arrangement, and one point of contact for the entire project.
Quality Control Across the Project
Our designers create plans based on what our construction team can build. They specify materials we trust and use regularly.
Our permit specialists understand local Markham requirements because they submit applications here every week. They catch potential issues before drawings go to the city, not after rejections cause delays.
Our builders are involved from the design phase forward. They know why certain decisions were made and understand the client’s priorities. This context supports better problem-solving when unexpected conditions come up during construction.
We maintain consistent standards across all phases. The attention to detail in our drawings carries through to the finished deck. There is no drop in quality when the project moves from design to construction.
Potential Drawbacks and How to Avoid Them
Hiring one company for everything can have risks if you do not choose carefully or lack the right contract terms.
Risks of Limited Options
When you work with a single company, you are limited to their design ideas and construction methods. If their designer only knows a few deck styles, you might miss out on solutions that better fit your yard or budget.
Homeowners sometimes realize halfway through that another company could have built the same deck for less money or with better materials. But once you’ve paid for permit drawings and signed a construction contract, switching contractors means starting over and paying twice for design work.
How to protect yourself:
- Get at least three quotes before committing, even if one company offers the full package
- Ask to see their portfolio during the first meeting and look for variety
- Make sure your contract includes a clear scope of work so you can compare it fairly to other options
- Request references from clients who used them for design and construction
- Do not pay large deposits upfront (10-15 percent is normal in Markham)
Ensuring Accountability
When problems happen, some companies may try to blame the design phase for construction issues, or vice versa. Since they control both, you have no third party to verify responsibility.
Consider adding contract language that makes the company accountable for the entire project. Your agreement should state that they are responsible for fixing any errors in the permit drawings at no extra cost, and that construction must match the approved plans.
Protections to include in your contract:
- Written warranties for both design accuracy and construction quality
- A clear payment schedule tied to completed milestones (permit approval, foundation inspection, final inspection)
- Proof of liability insurance and WSIB coverage
- A dispute resolution process in writing
Ask how mistakes are handled before signing anything. A trustworthy company will explain their process.
Comparing Single-Source Versus Multi-Contractor Solutions
When planning a deck project in Markham, the contractor structure affects how smoothly your project runs and what you will pay. Working with one company for everything versus coordinating multiple contractors creates different experiences in managing the work and controlling costs.
Project Management Differences
With a single-source deck company, all communication goes through one point of contact. You call us about design questions, permit issues, or construction updates. We coordinate between our designer, permit specialist, and build crew internally.
The multi-contractor approach means you are the project manager. You schedule the designer first, wait for drawings, then find someone to handle permit submissions, and finally hire a builder. If the builder finds problems with the design, you are left mediating between parties who have not worked together before.
Homeowners sometimes spend hours on the phone trying to figure out why their permit drawings do not match what the builder says is possible. When one company manages the entire process, these conflicts can be addressed before they become your problem.
Budget and Timeline Impacts
A single deck company provides one quote that covers design through construction. We know what our permit drawings will cost and how long City of Markham approvals typically take.
Hiring separately almost always costs more than expected. Each contractor adds their markup, and you may pay rush fees when delays from one contractor push back another’s schedule. Some customers have spent extra on designs that could not get permitted, then paid again to fix them.
Timeline gaps between contractors can add weeks to your project. Your designer finishes, then you search for a permit specialist, wait for their availability, submit to the city, then start looking for builders. With a single company, these phases can overlap.
How to Make the Final Decision
Ask each company whether they handle all three parts in-house or subcontract any piece out. If they subcontract the drawings or the permit work, you may be coordinating multiple parties.
Request a sample timeline that shows when design wraps, when permits get submitted, and when construction starts. A company that does everything should provide a clear, linear schedule.
Questions to ask:
- Who draws the permit plans, and are they on your staff?
- Do you pull the permit, or do I need to hire someone else?
- What happens if the city requests revisions to the drawings?
- Who schedules and attends inspections?
Check references from past clients who hired the same company for the full scope. Ask if the process was smooth or if there were problems between stages.
Compare quotes carefully. A single contract should list design, permits, and construction as line items. Make sure your contract states who is responsible for permit delays or design changes.
If a company cannot clearly explain how their designer communicates with their permit person and site crew, consider it a warning sign.
Responsiveness is important. If they are slow to answer questions now, they may be slow when you need a permit revision or a design change during construction.
Frequently Asked Questions
These answers cover the most common questions about hiring one company for deck design, permits, and construction in Markham.
What are the real benefits of using one contractor for deck design, permit drawings, and building?
You get one point of contact, one contract, and one team responsible for the full project. The designer and builder can coordinate early, which reduces unclear drawings, missed details, scheduling gaps, and disputes over who should fix a problem.
If one company handles everything, who is responsible if the permit application gets delayed or rejected?
The contract should clearly make the company responsible for preparing revisions and resubmitting the application. Confirm whether permit corrections are included in the quoted price and whether the project timeline will be updated if the City of Markham requests changes.
How do design changes during construction get handled when the same team does the drawings and the build?
The team can review the change, confirm whether it affects the permit, calculate the added cost, and document it in writing. Minor finish changes may be simple, while structural or size changes may require revised drawings and city approval before work continues.
Will a single full-service contractor cost more, or can it actually save money compared to hiring separate pros?
It can save money by reducing separate consultation fees, duplicated work, scheduling delays, and drawing corrections. However, compare detailed quotes because pricing varies by design complexity, materials, permit needs, site access, and the contractor’s scope of service.
What should I look for in a contract to confirm the scope covers design, permitting, and construction?
Look for separate descriptions of design, permit preparation, application submission, revisions, construction, inspections, payment milestones, warranties, and change orders. The contract should also identify who pays city fees and who is responsible if drawings need correction.
How can I verify the permit drawings match what will be built and meet Ontario Building Code requirements?
Review the drawings before submission and compare the dimensions, materials, footings, stairs, guards, and structural connections with your approved design. Keep the stamped permit drawings on site and confirm the crew follows them during each construction stage and required inspection.
